High-temperature-resistant heat insulation board and preparation method thereof

Abstract

The invention relates to a high-temperature-resistant heat insulation board. Comprising the following components in parts by mass: 12-14 parts of nitrile rubber, 6-9 parts of polyvinyl chloride, 6-10 parts of butyl rubber, 4-10 parts of ethylene propylene diene monomer, 2-3 parts of expanded graphite, 13.5-17 parts of paraffin oil, 1-1.6 parts of hydrotalcite, 10-15 parts of a composite foaming agent, 17-25 parts of a flame retardant, 1.6-3 parts of a filling agent, 1.3-3 parts of an accelerant, 0.45-4.6 parts of an activating agent, 0.3-2 parts of a vulcanizing agent and 0.6-2 parts of a plasticizer. Nitrile rubber, butyl rubber, polyvinyl chloride and ethylene propylene diene monomer are used as main raw materials, expanded graphite, paraffin oil and hydrotalcite are used as auxiliary materials, and a composite foaming agent, a flame retardant, an accelerant, an activating agent, a vulcanizing agent, a filling agent and a plasticizer are used as auxiliaries. The thermal insulation board is low in heat conductivity coefficient, good in heat resistance, good in heat insulation property, good in flame retardance, good in stability, safe and environmentally friendly, the flame retardance of the thermal insulation board is improved, and the thermal insulation board has the advantages of being low in heat release rate and little in smoke when a fire breaks out and can better meet the requirements of modern fireproof materials.

Description

technical field [0001] The invention relates to the technical field of heat preservation boards, in particular to a high temperature resistant heat insulation board and a preparation method thereof. Background technique [0002] Insulation boards on the market are usually divided into polystyrene foam insulation boards, expanded polystyrene insulation boards, extruded polystyrene insulation boards, polyurethane foam insulation boards, phenolic resin insulation boards and rock wool insulation boards. It has the characteristics of low coefficient, good thermal insulation performance, good waterproof performance and corrosion resistance, and is widely used in the insulation of roofs, floors, and basement walls. [0003] However, under long-term use, the current thermal insulation board is prone to deterioration in heat resistance, so that the thermal insulation effect of the thermal insulation board cannot be achieved. Therefore, there is an urgent need to develop a new type o...
